“We fixed the digital certificate problem and last evening resumed publishing new apps. It will take a day or two for the repair to fully deploy and newly-published apps to begin appearing in Marketplace again. If your app was in the process of being published, you don’t need to take any action. We have applied the fix and the app will continue through the certification and publishing workflow as normal.”

Of course as mentioned above that does not mean you can now instantly re-install or update those apps with issues as it can take time for the changes to rollout across their servers. Still, users should be begin to see updates by the end of the weekend.

Let us know in comments if you have had any success. Thanks, ThisIsMetro, for the heads up

Update was successful. Rad. Now I'm gonna force my Quantum to Tango. Keyboard has been disappearing lately and I am not willing to wait for ATT to push an update that they have never said would come for the Quantum.

The sad thing is that there's people happy just because of whatsapp...take my word, the last update of whatsapp might be the worst until now. If you uninstall the app, crappy WA is better than nothing, but if you have the old version, take my word. DON'T UPDATE.
